How This Calculator Works
Enter the contract price, then break out your costs: materials, labor, equipment, and overhead percentage. The calculator runs the numbers instantly.
You'll see your gross profit in dollars, profit margin as a percentage, markup percentage, and break-even revenue — color-coded so you can instantly tell if the job makes or loses money.
Know before you start whether a job is worth taking. Stop guessing on margins and start pricing with real numbers so every job you bid is one you can profit from.

Margin vs. Markup: The #1 Pricing Mistake
Confusing margin and markup is one of the most expensive mistakes a contractor can make. Here's the difference:
Profit Margin
Profit ÷ Revenue
$25,000 job − $20,000 costs = $5,000 profit
$5,000 ÷ $25,000 = 20% margin
Margin tells you what percentage of the customer's payment is actual profit.
Markup
Profit ÷ Costs
$25,000 job − $20,000 costs = $5,000 profit
$5,000 ÷ $20,000 = 25% markup
Markup tells you how much you added on top of your costs to get the selling price.
The costly mistake
If you want a 25% profit margin but apply a 25% markup to your costs, you'll only end up with a 20% margin. On a $100,000 job, that's a $5,000 difference. Multiply that across all your jobs and it adds up fast.
